TL;DR: In this paper, a frequency sharing approach is presented to smooth the effect of the highly intermittent nature of PV panels integrated with the shipboard microgrids, where a hybrid system based on an ultra-capacitor and a lithium-ion battery is developed such that high power and short term fluctuations are catered by an ultra capacitor, whereas long duration and high energy density fluctuations are cater by the lithium ion battery, in order to cater for the fluctuations caused by weather or variation in sea states, a battery energy storage system (BESS) is utilized in parallel to the

TL;DR: In this paper, parallel-connected bidirectional converters for AC and DC hybrid microgrid application are proposed as an efficient interface to achieve high performance operation, hierarchical control system is accomplished.

TL;DR: A delay compensator based on lead-lag compensation along with gain regulation block is designed to enhance the system stability against the communication delay and validate the effectiveness of the proposed methods.

TL;DR: In this paper, a method for voltage harmonic compensation in a microgrid operating in islanded and grid-connected modes is presented, which is done through proper control of distributed generators (DGs) interface converters.

TL;DR: In this paper, a tie-line power flow control of a hybrid MG, including photovoltaic (PV) generator, small wind turbines (WT), and energy storage units (ESUs), is proposed.
